Subject: [PATCH] build: add release build tasks with linker flags for smaller
 binary

Add -s -w linker flags to strip debug info and symbol table:
- cli:build:release - release build to ./bin/core
- cli:install:release - release install to system PATH

Binary size reduced from 19MB to 14MB (26% reduction).

Fixes #226
